摘要
采用有限元法对发动机气门进行了动力学及温度场的三维数值模拟,分别得出了气门在动载荷、温度载荷作用下的应力分布规律,研究结果为气门的失效分析和气门的优化设计提供了理论依据。
The dynamics and temperature field three-dimensional data of engine valve were simulated by using FEM.The regulations of the stress were found while valve is effected by the moving load and the temperature load.The study result provides theoretic basis for valve's invalidation analysis and optimizing design.
